Castaway Cove (港町ビッキーニ Port City Bikini) is also known as "The Seaside Paradise of the South", but it has the most unusual regulation rule and law: Everyone who comes there, even if it's only a short visit, must be required to become a "citizen" of Castaway Cove by wearing the proper outfit... a bathing suit. The Governor of Castaway Cove had some ridicule when he first had this idea. Everyone else used to rely on constant supervision to keep "bad tempered visitors" from the dark days (pirates, most likely) under control. The Governor reveals the genius of his peace-keeping vision: In a bathing suit, it's difficult to hide weapons! Because of that, the bathing suit at Castaway Cove is a sign of respect that should be worn at all times, and visitors who come there without one need not worry, as the the locals (most especially, the Governor himself) always has plenty to spare as generous give-aways.
